Why limit the number of VMs, rather than just have it limited directly by memory?

For example, why can't I have three instances with 2gb of memory and two with 768mb?

It would make it pull the trigger.

Wow, thanks for pointing out that connection. I enjoyed reading that book years ago -- I recommend it for anyone with any interest in sailing.

What do you mean, public IRC uses?
Larger hardware profiles will have higher server limits. These are the "Standard Small" hardware profile, so splitting it up into 4 servers seems sufficient for most people.

How many would you want to run on this hardware? 5?
That's what I'd take it to mean too, but the parent mentioned spokeo, which made me unsure if they were redefining the term to include anything public as they appear to harvest data from social media too. Official records are for most people pretty static, more familiar and more predictable than social media, and thus less dangerous, at least imho.

We are going to work with more community managers to help us push the usage - this implementation is useful for these guys who manage groups, who can't / won't implement chat solutions on sites.

I think some of the solutions that came before get taken over by trolls / spammers, so we're going with the oAuth approach, which we believe provides better content/conversation.

The empty room issue is still going to be a big one, we hope features like "trending" and that combination with push from community managers, can help resolve that issue.

We're going to try this again!

I'd imagine anything that attracts DDoS traffic. Generally speaking you know when you are hanging out in rooms where people are willing to DDoS you to kick you offline.
It is indeed a lot of assumptions and also ignores, for example, the fact that those shared and least-interesting features are still, in many cases, what people like most about things, which would make it a good approach for a recommendation engine even though it's a bad approach for critical work. Musical and narrative genres are rife with this kind of 'subscription mentality'[1]: people who simply enjoy the genre and will like almost any entry into it.

> Secondly I can imagine taxonomies which are not based on shared textual features, but on chronological, geographical, and genre features.

Note that these aren't meant to be excluded by the quote, which is from a book that deals largely with the three things you mention. Il n'y a pas de hors-texte and all that.

> Thirdly, I don't see why a shared feature would automatically be the "least interesting". What's interesting is rather subjective and context-dependent. If for example I had a particular interest in literature coming out of the first world war, this shared feature could be at the top of my list.

No doubt, but the quote is specifically concerned with literary/artistic value. Historians or critics reading through a different lens will of course have different interests and see value in different things.

Would you not agree, though, that a particular interest in literature coming out of the first world war is simply a filter for your data set, and that once you get down to specific works, it's how they differ or assert themselves against one another that is most interesting about them?

1. I just made that phrase up; someone may have come up with a better one already. But you know the type: the inveterate sci-fi fan, the fantasy aficionado, the lover of all things zombie. These people are less concerned with the quality of a particular work than with the genre trappings it exhibits.

Sorry about that. Updated the title. I have been increasing the limit repeatedly to make room for more people, but it looks like there's going to be far more than I can allow in right now ;-)

This is pretty poor password security, but they also provide other levels of security.

If you use the 2 password method, your backup archive is then further protected by one that you cannot simply reset. If you forget this password, you might as well say goodby to you backups.

The last security method involves using your own keys. This is also not easily reset without destroying your backup archive.

There is at least some comfort knowing that even if the account is compromised, your data is still inaccessible...
> I'm not sure how 'Source Code Version Control' and 'Build Automation' is anywhere near the words 'Software Engineering'.

I'm not sure how they couldn't be. True, they are not a part of computer science, but both are very helpful to be able to build software efficiently (i.e. software engineering). The places I've worked tend to not have build managers (and the one time there was one, the person wasn't technical and needed 'help' from engineering, to have sane policies and organization). Both skills are also important if you want to launch something -- either a personal project (open source or otherwise), or on a small team at a startup.
My school didn't teach B-trees, though they did teach 2-4 trees. I've never really been in a situation where I've needed to use a B-tree; and, I was an accomplished competition programmer in college.

That said, I looked up on the internet what they were and it was pretty easy to follow.
Would have loved to have helped!

You're not alone in cobbling together a solution, there are a ton of people in that bucket. We want to make Vero the tool that not only helps people save time building their own solutions but allows them to send better campaigns (i.e. better reporting and internal smarts).

The blog posts with examples are hopefully helpful even if you're not using our system!

+1 @davidtyleryork, we've been doing the same. Customizability is always a concern for us but we will definitely take a close look at this.
If you are launching an app, you get a tangible benefit from a marketing launch, which probably derives from Apple's DNA.

On the App Store, if you do zero marketing, you will likely have your most total downloads the day after your app is approved. The first day, you likely only get a half day, and you have to wait for full propagation on iTunes. Also, the rankings are a moving, weighted average, so unless you have a terrific spike, you need to wait for your average to start kicking in before you move up the charts.

Day 2 or 3, you will peak, then rapidly decline. So, it makes a lot of sense to time your marketing boom for the day after your approval, or rather the first full day of being live on the store. Marketing tends to be multiplicative.

People make the mistake of thinking app rankings get you sales over the long haul - it's more the other way around. But at the beginning, you get a bump, and you should use it. This bump derives from several sources:

* new list on App Store

* lots of robotic websites and Twitter accounts spamming about new apps

* the press cares about "news"

* energy from your team on a specific launch - people tell their friends and social outlets, and actual planned outreach by the company

* Apple featuring you in category or on home page of iTunes

Think of it as trade credit. The rationale for much of trade credit is that the supplier knows a great deal about the firm, so they are able to make a well-informed lending decision [0]

In contrast, banks may not know much about firms (or only know obsolete information), so the usual information asymmetry [1] issues arise

Yes, I used my own 448 bit key, so no one can see my data. But they still can destroy it, or just change it to where it no longer backs up what I want it to, and I'd have NO IDEA unless I constantly checked my settings.
This process sounds perfect for launching an app with a soft launch, while holding a launch event a few days later.
For one thing that's what I'd expect based on the title (since the site already launched). If the site hadn't launched, then a link to a relatively contentless news story would be fine.
Definitely a common problem. Awesome to hear you have something setup though, that's a step ahead of most!

Tracking metrics properly would help you take it every further.

Intercom is (in my opinion) more closely related to a CRM. It's messaging features are quite powerful and give you the ability to do support and in-app messaging really easily.

In contrast, our focus is squarely on email right now. We make it easy to setup sophisticated campaigns, use custom HTML templates and do A/B testing - all the good stuff you'd expect when dealing with emails. On top of that we want to make it easier to send better campaigns by building out tools that really help you drive your conversions higher. Reporting is a big part of that, as is sharing real-world examples!

Naming it "A/Bingo" and hosting it on his own site?

Nah.

Naming it "A/Bingo" and hosting it on his own site for the intent of garnering linkjuice while at the same time presenting the name choice as simply a guileless, clever pun (as he does in his announcement of the project [1]) and within the context of his normal policy of broad disclosure?

A little bit. Perhaps "grey hat" is too strong a word. Swap in "a little discomfiting".

(To clarify, my discomfort is due to the tying together of two orthogonal axes, ie, the quality of Bingo Card Creator as a result for the keyword "Bingo" and the quality of Bingo Card Creator as a source for an A/B testing framework.)

Nice to see pricing addressed.

SMS Spam from a Y Combinator Company?
This morning (at 2am!) I started to get a bunch of text messages from a domain called "theflockapp.com."

There's no opt-out & no way to tell them to stop texting me (especially at 2am!).

I checked their FAQ & couldn't find anything there:
https://theflockapp.com/faq

However, I surprised to find that it's an app created by a Y Combinator company, as the FAQ links to their team page:
http://bu.mp/company/ourteam

The link in their text spam only takes me to download their app.

The best I can figure, is that to get them not to spam me, I have to 1) download their and 2) give them access to my Facebook account.

For reals?

PG or anyone else, could someone please ask them to knock this type of behavior off? It really does seem over the line.

I think you're a bit confused. There's a difference between copying and imitation. For example, all cars may have driver seats, but no two driver seats are identical. They all differ in material, shape, color, comfort, adjustability (or even adjusting mechanism)...

What does not lead to progress is imitation, where the feature in question is copied to be completely identical without any incremental improvements or adjustments for context.

"The Pinterest Layout" is just another tool in the toolbox of a good designer, and many designs already features similar patterns way before people started pinning. It's only natural that successful sites get copied, but that doesn't make it a good thing.

SBNation.com recently rebranded all it's fan-sites (such as Celticsblog.com, Silverscreenandroll.com and many dozens of other American sports-related sites) and went for a full-on visual approach.

However pretty it looks, for a bunch of sportsblogs it seems like the wrong approach. Content got scattered and the mobile (responsive) design makes loading it (even on wi-fi) a pain in the rear.

Yeah, this one is a trend that, imo, can go f itself.
good luck, mate! Loving to be behind the scenes :)
This is not spam, I am describing what my site is about which includes the categories.
I don't have any inside information on how Apple will do things in iOS, but I see no reason why they couldn't do that.

"Services" have been part of iOS/OS X since the late 80s/early 90s with NeXTStep, the precursor to both.

I don't think Apple is deliberately not allowing services/intents in the manner you describe, I think it's just taking them a long time to figure out how to do it within the process and security model they are trying to enforce in iOS.
I co-founded a company a decade ago that spent most of its marketing budget on AdWords, on the order of $120K a month. We were constantly running into issues with the credit card company triggering their fraud algos and killing our campaigns, despite having these charges regularly coming from the same company (Google).

At some point if you're Google you get tired of letting the banks skim 3 percent ($3.6K a month!) off the top of these high-volume transactions and prevent your customers from spending. Google knew we were certainly good for the money by the time we'd been doing it for a few months. This kind of cash squeeze is why all sorts of companies get into financing, like GMAC for auto financing and Dell for computer financing.
Great idea. Make a mobile app with an incentive so people can ID images to waste time. Focus on fine tuning an algorithm by checking against what people say and we could be on our way to making a really good image processor.
The MySpace layout is what happens when too many people are working on a product. It isn't being built around a job to be done, it seems that they are simply redesigning shit for the sake of redesigning shit.

Any product should ultimately be built, optimized, and if necessary, redesigned to best perform a job. Too many sites are just piggy-backing on other site's success because they simply don't know what else to do. In their mind I'm sure it seems like a great idea, but then nobody uses it. It's because the changes are not being made out of necessity. How do more people not see this?
It's still what computers often spend a lot of time doing. What do you think your database engine is doing most of the time? Those indexed columns aren't just there to smile warmly upon your data.
I believe that they were talking specifically about the programs which create orders which are never fulfulled. That way their programs creating real trades have an advantage (since they are running on servers located closer to the exchanges).

This isn't an entirely unique scenario, as there are other establishments not unlike this one that, once they achieved critical mass in awareness, simply gained intolerably long waits.

This could be viewed as either an inability or unwillingness to scale. ("Inability" could be inherent in the effort, as in there is just not a feasible means to scale effectively.)

I have to admit that I'm impressed at how well the system they build compensated for the mechanical failure. It looks like they have some good people building things.

One aspect that's worth consideration is the private/corporate aspects of spaceflight. When there were failures in Apollo and the shuttle, the public had a right to know everything that happened since we'd paid for everything. SpaceX has been super cool about disclosure here, but how long can we count on that? At some point, there's too much money at stake for them to maintain full transparency.
Nice.

Hijacking this thread but...

"Plentiful for the cost" is an oxymoron to "great restaurant"

Okay maybe that's a little bit flippant but seriously, judging a restaurant based on quantity of food for cost is apparently a very American thing and one of the reasons food is so bad here in general

http://www.amazon.com/gp/aw/d/0767920562 had a chapter on how different cultures think about food. Having lived in a different one for several years that valued flavor over quantity I wish there was some way to influence America's culture more in that direction. It might also help our obesity issues. I'd much rather have a small scoop of unique and delicious ice cream than the tubs that some of the most popular American chains dish out
This is a rather narrow viewpoint of what makes a great programmer in my opinion. One completely missed element here is the ability to track organizational complexity. For example, you have a site with 100,000 lines of code. Making one change somewhere affects 10 other things elsewhere, each of which might affect another 10 things. Keeping track of all that is what I'm talking about. Same skill you find in great chip (integrated circuit) designers. Personally I think it's far more important than some of the concepts here, which focus mainly on algorithm-level stuff.

To my eye the Pinterest masonry grid is a trick for creating 'false excitement' around the content. In that way, it's like rapid edits or a shaky camera in video.

This works for a while, in certain domains, for people in certain leisurely modes of operation... but can also eventually lead to frustration and distrust. ("Why is this page making it hard for me to do an thoughtful review of what's new or important?")
Yep, the site says clearly that it is in alpha.
